There are many different microcontrollers on the markettoday that are being used in embedded controlapplications. Many of these embedded control systemsneed non-volatile memory. Because of their smallfootprint, byte level flexibility, low I/O pin requirement,low power consumption, and low cost, serial EEPROMsare a popular choice for non-volatile storage.Microchip addresses these needs by offering a full lineof serial EEPROMs covering industry standard serialcommunication protocols for two-wire, three-wire, andSPI communication. Serial EEPROM devices are availablein a variety of densities, operational voltageranges, and packaging options.
